039D: Chinese latest AIP submarine, packed with new missiles and solid-state batteries

Chinese 039D submarine appears in a new video posted online, with its unique sail. This latest PLA conventional submarine has a notch in the forward edge of the sail. It is very similar to Swedish A26 submarine sail design, improving stealth and internal space. Some believe that the new sail of this 039 submarine variant can divert waves when it is cruising high-speed on surface, or in rough seas. The notch will push water away from crews. 039D maintains extended hump design from earlier 039 improvements, possibly learned from Kilo class. Overall living condition for the crew also receive major improvement, better to suit long duration missions. A26 appears to have much more fine-tuned curves comparing 039D, but it might be due to the only 039D submarine is just an early prototype, not a finalized production model. 039 submarine is the latest family of Chinese diesel-electric powered underwater platform. 039A is the first upgraded variant with a huge sail, and with many improvements. Early design of the sail of 039 is believed to be too complicated, and increasing drag/noise. 039B and 039C has smoother sail design, reducing drag and noise signals. 039C is believed to be the first fully upgraded variant with advanced technology overhaul. YJ-18 and YJ-8 anti-ship missiles can be launched from any 039 family submarines. YJ-18 family also include land attack and anti-submarine variants, bolstering 039's capability. Various types of Chinese torpedo give 039 family capability of destroying large-size vessels. 039D may be based on new lithium-ion propulsions, or a new AIP system, reducing the need of outside air. Chinese solid-state batteries might have been tested by one of the 039 submarines. This new battery technology has better safety record and greatly reduced thermal runaway.
